April is the time when the spring farming is busy. At this time, the temperature is gradually rising and the rainfall is gradually increasing. It is a good time for farmers to plough spring farming. All kinds of vegetables need to be planted, nursed, planted, managed, and prevented from pests and diseases. The following series of vegetables are compiled in a small series of vegetables in April. Farmers will come and see.

1, sowing, seedling

Cabbage, radish, spinach, celery, medlar, sage, leeks, bamboo leaves, stalks, cowpeas, edamame, lentils, peas and potatoes in the open field; cucumber, medlar, cowpea, cabbage in the open field; ginger to be germinated Replay.

2, planting

Solanum, melons, beans, lettuce, bamboo leafy vegetables, bean peas, etc., are covered with mulch or open field.

3. Field management

The temperature is suitable, the seedlings grow rapidly, and the plants should be planted in a timely manner. Due to continuous rainy or insufficient manpower, when the plants cannot be planted on time, the nutrient meal should be discharged, the nutrient area should be expanded, the watering should be controlled, and the seedlings should not be squeezed to cause a long time; It not only increases the multiple cropping index, but also helps to change the microclimate in the field. For example, the lettuce crops are planted with melons, beans and other vegetable crops. The effect is very obvious. Before planting, it is necessary to do a good job in deep cultivation, soil preparation, and application of base fertilizer. Various work.

All kinds of vegetables in the shed should be removed from the shed in the shed, finely managed, combined with the weather conditions, to release the wind, drain and cool, and create good environmental conditions for crop growth.

Tomatoes, cucumbers, kidney beans, and cowpeas should be laid in time to prevent lodging; tomatoes should be sprayed with tomato to protect flowers and fruits; all vegetable crops should be sprayed with potassium dihydrogen phosphate; melon crops should be artificially polled; melons 3-4 When spraying leaves, it can be sprayed with ethephon, which can increase the yield early; the cauliflower and celery should be sprayed with borax solution for topdressing. The celery should be sprayed with 9200 liquid (1g powder plus 50kg) to increase production and improve quality. Pay attention to cultivating and make the soil breathable. To ensure the normal growth of crops; vegetables covered with plastic film, when planted, properly watered to prevent excessive humidity, resulting in rotten root dead seedlings; vegetables cultivated in open field, pay attention to cultivating and weeding, solve weeds and vegetables glory, competing for fertilizer contradiction.

(1) Plastic large and medium-sized tomatoes, peppers, eggplants, cucumbers, and zucchini. After the middle and late of this month, as the temperature rises, the large and medium-sized sheds should be ventilated day and night. At the same time, attention should be paid to the door fruit and the root melon. Early harvesting to facilitate plant growth and upper results.

(2) Spring cabbage, spring lettuce, winter radish should continue to do the work of clearing the ditch, and pay attention to timely harvest.

(3) Garlic (garlic cloves, garlic cultivation): 3 to 4 days before picking, stop watering, carry out cultivating loose soil, in order to convulsion. After picking, pay attention to keep the soil moist; timely watering in case of drought, and apply 10~15kg of ammonium sulfate per acre to promote the garlic head. 5 to 7 days before the garlic is received, stop watering to avoid rotten garlic and loose petals.

(4) Radish: The radish sowed from February to March, when the true leaves and the “broken belly” are used, the seedlings are once in a row, and the row spacing is 17-20 cm square. Before the seedlings are fixed, the septic debride water is twice. After the "breaking belly", the straight root began to expand and apply heavy fertilizer, applying urea 10 to 12. 5Kg per acre and paying attention to pest control.

(5) Spring Chinese Cabbage: Spray 0.3% to 0.4% of potassium dihydrogen phosphate solution 4 to 5 times for top dressing during the whole growing season. Do not dry or water, and control soft rot, downy mildew and anthracnose .

(6) Amaranth: If planted in plastic large, medium shed, a seedling, it is necessary to pay attention to ventilation, watering. When the temperature of the shed reaches 20~25°C, the opening is ventilated. When the surface of the shed is whitish, the water is sprayed with a fine-hole watering can. Generally, it should be carried out at noon. The outside temperature reaches 15~20°C, and all the plastic film is uncovered, which avoids the high temperature-induced disease. And meet the water requirements of seedlings.

When a piece of real leaves, start topdressing, use 20% of the decomposed human and animal excrement in a fine watering can, and then apply 30% of the decomposed human and animal excrement, ammonium sulfate and superphosphate every 7 to 10 days. That is, 300 g of ammonium sulfate and 1-2 kg of superphosphate are added per 1000 kg of manure water, and the fertilizer should be applied after each harvest or dredging.

(7) Amaranth (spinach): After the emergence of seedlings, the application of decomposed human and animal manure and water to the water 3 times the application of seedlings, the whole growth period should pay attention to watering, topdressing, in order to keep the soil moist, plant nutrient sufficient and vigorous Growing. After each harvest, pay more attention to timely watering and topdressing.

4. Pest control

Pay attention to the control of tomato gray mold, early blight, late blight, brown rot, eggplant brown streak, cotton blight, melon vegetable anthracnose, lettuce downy mildew, sclerotinia, etc., pay attention to control aphids, yellow guards, small tigers , yellow curved stripe jumping, diamondback moth, cabbage caterpillar, spotted fly and so on.

5, harvest

Cabbage, radish, carrot, cabbage, lettuce, sage, scallions, spinach, leeks, kale, cauliflower, cucumber, melon, loofah, zucchini, kidney beans, kidney beans, tomatoes, eggplant, pepper, leeks, bamboo leaves, sunflower , è—•, etc. can be harvested.

The above is the vegetable planting in April compiled by Huinong. The farmers can grow vegetables according to the actual situation. The above planting techniques and pest control can also be mastered. I hope the above content can help the farmers.
